Wiping the inside glass

[likwid]

Hey guys,

I just set up my tank. I would slowly add saltwater to it 4 gallons at a time, with hour long breaks in between. Doing this left streaks on the inside of my glass where the water would sit. Since the tank is now full of fresh, clean salt water, what is the best way to clean off those streaks? I do not have an algae magnet or scraper yet, so it would have to be a household item (cloth, brush, etc), but I want to be careful not to add any contaminates or dirt to the water when I am doing so.

Thanks
